Section 5: Maintenance
An O–Ring Maintenance Kit is provided with your pressure
washer which includes replacement o-rings, rubber washer
and water inlet filter. Refer to the instruction sheet provided
in the kit to service your unit's o-rings. Note that not all of
the parts in the kit will be used on your unit.
To remove a worn or damaged o–ring, use a small flathead
screwdriver to get underneath the o-ring and pry it off.
